wiiirrnnrnnn HOOK.

Application filed November 13, 1923.

T 0 all whom it may con-0cm:

Be it known that 1, 015mm? C. YSTENESS, a. citizen of the .United States, residing in Bejou, State of .Minnesota, have invented certain new and useful Improvements in Vhiflietree Hooks, of which the following is a specification. 1

This invention relates to whiflletree hooks, and has for its primary object the provision, in a manner ashereinafter set forth, of a hook so constructed that the eye of the tug strap when placed thereupon may be secured against displacement when the tug strap becomes flat. 1

A further object of the invention is the provision, in a manner as hereinafter set forth, of a whitiletree hook having suinging means for locking the eye of the tug strap thereon and further so constructed that when the tug strap eye is put under strain, the entire pressure will be put upon the hook and no strain will be put upon the lock portion.

A further object of the invention is the provision, in a manner as hereinafter set forth, of a whiffletree hook having its free end extending inwardly at a slight curve to provide a guide for the tug strap eye, to expedite the application of the eye to the hook. y i

The final object of the invention is the provision, in manner as hereinafter set forth, of a whifiletree hook of simple structure, few parts, strong, durable and inexpensive to manufacture.

The invention will be best understood from a. consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding that the invention is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings Figure 1 is a top plan view of the device embodying this invention, being shown applied to one end of the whiflletree.

showing the position occupied by the lug eye, when it is desired to open the hook and remove the eye therefrom.

Fig. 4 is a perspective view of the device embodying this invention, showing a difierent method of application to the whililetree, than the method disclosed in Fig. 1.

Referring now to the drawings in detail wherein like numerals of reference indicate corresponding parts throughout the several figures of the drawing, numeral 1 indicates one end of the whil'lletree, to the forward face of which the device embodying the pres:- ent invention is secured. This device comprises a substantially L-shaped bar 2 having the lower flanged portion 8 extending forwardly of the whiflletree body thus bringing the back of the upright portion against the surface of the whiffietree. This vertical portion 2 has provided therein passages for the insertion of bolts 4 by which the device is secured to the whiflletre-e. It is of course understood that other means may be employed for securing the device to the whifiletree, and as shown in Figure 4. of the drawings, a ferrule 5 is provided which surrounds the end of the whiflietree and through which the bolts 6 pass to secure the ferrule in position. Two forms haverbeen shown for securing the device to the whiifietree, but it is of course to be understood that any appropriate means may be made use of. The following description of the device will be confined to the showing of Figure 1 and its related figures in order that the specification may read clearly.

The hook comprises a U-shaped body portion 8 having the shank 7 formed integrally with the outer portion of the whiflletree connection 2, and where it connects with the connection 2, it is of the same width as the connection. This shank extends forwardly a short distance when it is cut downwardly from its upper edge at an angle to provide a sloping portion 9, the lower end of which sloping portion terminates in a vertical portion 10 which merges into the body of the hook 8. The under portion of the hook, as clearly shown in Fig. 3, is verynearly in the same plane with the bottom of the flange 3. The inner or free end of the hook 8 is extended, into a substantially elongated slightly inwardly bowed tongue 11. This. tongue 11 is positioned forwardly of the flange 3 in substantially parallel relation thereto, a suiiicient distance to allow the passage of the tugstrap eye indicated at 12, thereover, without binding between the two parts.

Means is provided for locking the tug strap eye 12 upon the hook S, in the form of a fiat U-shaped hook member 13, the free end 1 1 oi which is upon the side of the hook 8 opposite to its tongue 11, this hook 13 being formed fiat to lie upon the fiat surface of the hook 8, and when positioned thereupon the end 1 1 lies adjacent the vertical wall 10 of the hook 8. The hook 13 has a shank member 15 which extends inwardly across the inside oi the hook to a point in line with the central part of the free end 1st, whereupon the shank is bent rear-wardly at right angles to the body portion 15 to provide the flat bearing member 16 which bears against and is bolted to the inner surface of the shank 7 of the hook 8, by means of a bolt or rivet 17.

As clearly shown in Figure 1, the crotch 18 of the hook 13 is cut deeper than the crotch of the hook 8, and when the tug strap eye 12 is in position, it does not touch the crotch 18 of the hook 13, but bears only against the hook S. The hook 13 is also made of sutticient length to overlap the hook 8 when the two hooks are brought together, this overlapped portion indicated at 19, serving as a grasping tab to liftthe hook 13 from the hook 8.

hen it is desired to remove the tu strap eye from the hook, it is necessary that the eye be swung outward toward the outer end of the whifiietree and then swung upwardly and laid back upon the sloping portion 9 of the shank of the hook 8, as shown in Figure 3. In this position, the hook 13 may be raised and passes easily over the eye 12, whereupon the eye 12 is swung outwardly and downwardly and then in and across the tongue 11 of the hook 8, to be removed.

What I claim is 1. A whiffietree hook con'lprising, a. U- shaped body portion having one end of greater length than the other, an angular-1y disposed attaching means extending from said long end, a guide tongue extending at an angle from the other end and substantially in parallel relation to the attaching means, and closure means for said body portion comprising a hook having one end piv otally secured to said long end upon its inner side and adapted to rest upon said body portion when in engaged position, said clo sure hook having its crotch cut deeper than the crotch of said body portion to avoid contact with an engaging member, and further having its outer portion extended beyond said body portion to provide a finger engaging tab.

2. A whifiletree hook comprising, a U shaped body portion having one end of greater length than the other, an angularly disposed attaching means extending from said long end, a guide tongue extending at an angle from the other end and substantially in parallel relation to the attaching means, a closure means for said body portion comprising a. substantially U-shaped hook member having one end turned inwardly to extend across the body of the hook and pivotally secured to said long end upon its inner side, said hook member being adapted to rest upon said body portion when in engaged position.

In testimony whereof, I aiiix my signature hereto.
